Flask slide fitting



FLASK SLIDE FITTING Filed llay 3, 1928 IN VEN TOR. d e/60a 5012a ILE-4AM A TTORNEY Patented Feb. 11, 1930 PATENT OFFICE STEPHEN BONA, FBRIDGEPORT, CONNECTICUT FLASK SLIDE FITTING Application filed May 3,

The main object of the invention is to provide a flask slide fittingconsisting of a guide pin, and a follower of novel and improvedconstruction adapted to be associated with .5 said guide pin in suchmanner as to insure that there will be no tilting, shifting, or rockingof a member or section of a flask while being associated with or removedfrom a different section or member of the flask.

With the above objects in view, as well as others which will appear asthe specification proceeds, the invention comprises the construction,arrangement and combination of parts as now to be fully described and as15 hereinafter to be specifically claimed, it being understood that thedisclosure herein is merely illustrative and intended in no way in alimiting sense, changes in details of construction and arrangement ofparts being permissible so long as within the spirit of the inventionand the scope of the appended claims. v

In the accompanying drawing forming a part of this specification,

Fig. 1 is a front elevational view of a flask slide fitting in which thefeatures of the invention are incorporated, disclosing parts of the dragand cope sections and the pattern or match plate of the flask inelevation;

Fig. 2 is a side elevational view of the fitting, disclosing the dragand cope sections and the pattern or match plate of the flask insection;

Fig. 3 is a central vertical sectional view of the fitting, disclosingthe drag and cope sections and the pattern or match plate of the flaskin section;

Fig. 4: is a top plan view of the fitting; and

Fig. 5 is a top plan view of a flask having two fittings made inaccordance with the in vention.

The flask illustrated consists of a drag section 10, a cope section 11,a pattern or match plate 12, and a plurality of flask slide fittings(usually two), represented generally at 13, designed with the purpose inview of insuring that a part of a flask while being placed upon orremoved from a stationary part of the flask, will be caused to travel ina vertical plane, directly toward or away from said 1928. Serial No.274,911.

stationary part, without tilting, shifting, or rocking relativelythereto.

In Fig. 5 I have disclosed two flask slide fittings 13, at oppositesides or ends of the flask. These may be duplicates, and but one need bedescribed.

A bracket ll removably attached to a face of the dra section, as byscrews 15, includes. spaced apart bosses 16 cut away to providevertically aligned depressions 17. A vertical guide pin 18, situated inthe depression 17, is removably secured to the bosses 16 in anyconvenient manner, as by screws 19. The guide pin is desirablycylindrical, but could be some other suitable shape.

A bracket 20 has slots 21 in its inner edge adapted to receive smallbolts 22 passing through tl e pattern or match plate 12. Nuts 23 uponthreads of the bolts 22 and adapted to engage the lower face of saidbracket 20, complete a construction making provision for removablyattaching the bracket 20 to the pattern or match plate in such mannerthat said bracket can be adjusted inwardly and outwardly of the patternor match plate and securely fastened down at any desired position, aswill be obvious. A vertical part 24: of the bracket- 20, extendingthrough an opening 12 in plate 12, has inwardly extending, spaced apartears 25 between which a web 26 of a follower 27 is pivoted as indicatedat 28. The face of the follower is shaped to preferably embrace theguide pin 18 throughout approximately one-half of the circumference ofsaid pin, and the axis of the follower is desirably situated at aboutits midlength. (See Fig. Small coil springs 29 having their oppositeends fitted. upon protuberances 30 and 31 of the vertical part andfollower, respectively, at the upper and lower extremities of saidvertical part and follower, serve to cause the follower to normallyassume vertical position to more easily find the guide pm.

A bracket 32 removably attached to the cope section, as by screws 33,has a horizontal part 34 extending outwardly from the cope section andprovided with an opening 35. A bracket 36 has slots 37 in its inner edgeadapted to receive small screws 39 entering the horizontal part .34 andadapted to function in about the same manner as the nuts 23 to removabland securely attach the bracket 36 to the horizontal part 34 and allowinward and outward adjustment of the bracket 36. A vertical part 41 ofthe bracket 36 has inwardly extending, spaced apart ears 42, similar tothe ears 25, between which a web 43 of a follower 44 is pivoted asindicated at 45. The face of the follower 44 is shaped to preferablyembrace the guide pin 18 in about the same manner as the follower 27,and the axis of said follower 44 is also at its midlength. (See Fig. 3.)Small coil springs 46 and protuberances 47 and 48 on the vertical part41 and the follower 44, respectively, at the upper and lower extremitiesof said vertical part and follower, function to cause the follower 44 tonormally assume vertical position to more easily find the guide pin, inprecisely the way as already described in connection with follower 27.

The manner in which the flask slide fitting operates will be apparent.In Fig. 5 a set of fittings are arranged opposite each other upon thesides or ends of a flask. In practice, when associating the pattern ormatch plate with or removing said plate from a flask section, or whenassociating a flask section with a different flask section or with thepattern or match plate or removing said flask from said different flaskor plate, the part of the fitting being moved should be positivelyguided by the part of the fitting remaining stationary, in order thatthere can be no tilting, shifting, or rocking of the member being movedrelatively to the stationary mem- It will be obvious that either of thefollowers 27 or 44 will of necessity embrace the guide in 18, no matterwhether said guide pin is s anting toward or away from the flask, duringthe entire passage of the follower along the guide pin, for the reasonthat the upper and ower portions of the follower can swing about thefollower axis, toward and from the guide pin, and the arrangement willbe particularly effective to prevent sidewise tilting of the part of theflask being put in motion during association or disassociation of flaskparts.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is:

l. A flask slide fitting comprising a guide pin secured to a flaskmember, a follower for said pin, a bracket upon a different flask memberpivotally supporting an intermediate portion of said follower, and coilsprings between said bracket and end portions of said follower. i

2. A flask slide fitting comprising a guide pin secured to a flaskmember, a follower for said pin and adapted to embrace a portion only ofthe perimeter thereof, a bracket upon a different flask member pivotallysupporting an intermediate part of said follower, and coil springsbetween said bracket and end portions of said follower.
